Print Shop File Requirements
What every commercial print shop expects — and how to deliver files that print correctly first time.
Commercial print shops have specific file requirements that POD sellers often overlook. Submitting files that don't meet these requirements causes rejections, color shifts, or printed output that doesn't match your design. Most shops have similar requirements: 300 DPI resolution, CMYK or sRGB color, bleed on edges, embedded color profile, and PDF or high-quality JPG/TIFF.
This guide covers the universal spec list that satisfies 95% of commercial print shops, plus the specific quirks of major shop types.
Standard Print Shop Spec List
| Spec | Standard | Why |
|---|---|---|
| Resolution (DPI) | 300 DPI at print size | Industry standard for sharp print quality |
| Color Space | CMYK (offset/commercial) or sRGB (digital/POD) | Matches printer's calibrated workflow |
| Color Profile | ICC profile embedded | Ensures color accuracy across devices |
| Bleed | 0.125" on each side | Prevents white edges after trimming |
| Safe Area | 0.25" inside trim line | Critical content stays in printed output |
| File Format | PDF (preferred), TIFF, or high-quality JPG | Lossless or near-lossless for production |
| JPG Quality | Quality 95+ (Photoshop 12) | Avoid compression artifacts in print |
| Fonts | Outlined or embedded | Prevents font substitution |
| Filename | Descriptive, no spaces, version number | Easy identification in shop's queue |
PDF preset: "PDF/X-1a" or "Press Quality" satisfies 99% of commercial print shops. Use this preset when exporting from Photoshop, Illustrator, or InDesign.
Why this matters
Commercial printers have calibrated workflows for predictable output. Files that don't match their specs get rejected (you waste turnaround time), printed wrong (you eat the cost), or printed with color shifts (customer complaints). Knowing the universal spec list lets you prepare files once that work at any shop. The cost of getting it right: 10 minutes of preparation. The cost of getting it wrong: lost orders, refunds, and reprints.
By Print Shop Type
Online POD platforms (Printful, Printify, Gooten):
- Use their template files (download per product)
- Color: sRGB (digital workflow)
- Bleed: included in template
- Format: PNG (with transparency for apparel) or JPG
Local print shops (FedEx Office, Staples, local copy shops):
- PDF preferred (any version)
- Color: sRGB usually fine; check for CMYK requirement
- Bleed: 0.125" if edge-to-edge design
- Format: PDF, JPG, or TIFF
Commercial offset printers (high volume, books, brochures):
- PDF/X-1a or Press Quality preset required
- Color: CMYK with embedded profile (Coated FOGRA or US Web Coated)
- Bleed: 0.125" minimum, often 0.25"
- Fonts: outlined or embedded subset
Specialty print (fine art, large format, banners):
- TIFF preferred (lossless quality)
- Color: depends on shop calibration; ask first
- Resolution: may accept 150 DPI for very large formats (24×36+)
- Custom requirements per material (canvas, metal, acrylic)
Common mistakes
1. Submitting RGB to a CMYK-only commercial printer
RGB → CMYK conversion at the shop produces color shifts. Convert in Photoshop first using the shop's recommended profile. Soft-proof to preview shifts.
2. Forgetting bleed on edge-to-edge designs
Without bleed, trimming variance creates white edges. Add 0.125" bleed per side and extend design into bleed area.
3. Live text without outlining/embedding fonts
If the shop doesn't have your font, they substitute → text looks different. Outline text in Illustrator, or embed fonts in PDF export.
4. Using JPG below Quality 90 for commercial print
Compression artifacts visible at print scale. Always use Quality 95+ for print, or use TIFF/PDF for lossless.
5. Not soft-proofing before submitting CMYK files
In Photoshop: View → Proof Setup → Custom (set to shop's profile). Shows how colors will shift in print. Adjust before submitting.
